River and sediment flooding is impacting many communities worldwide. This is due to significant geographic changes; areas once sparsely populated are now filled with growing cities, exposing new communities to an increased risk of extreme weather events. To avoid catastrophic damage, various countermeasures should be planned and implemented, including forward-looking urban planning (e.g., flood maps, flood plain management), insurance systems, transforming human behavior, analyzing socio economic impact and policy for relocation from vulnerable area. It is also important to foster a culture of preparedness in society. To do so requires disaster risk reduction beyond traditional programs by employing advanced technology such as virtual and augmented reality. Lessons from past critical situations, including ones under the COVID-19 pandemic, should be studied and shared. Effective restoration programs should be developed to support communities recovering from disasters. Ecosystem-based disaster risk reduction (Eco-DRR), such as nature-based solutions and green infrastructure, deserves due attention for its central role in strengthening the coherent implementation of various international frameworks under the 2030 Agenda for Sustainable Development.
